Hi Judy!
A thousand welcomes to you!. You have definately come to the right place for support, advice , and motivation - it always helps me to stay on track.
Your plans sound great - you are right about the exercise, it will really make a difference to your weight loss, and also your fitness levels. Just build it up gradually - and find something that you enjoy and can do regularly, such as walking.
There are lots of different challenge and support groups which you can find on the support page - I'd recommend joining one of them as you get alot of individual support and it also helps you to be accountable. I belong to the 'time for serious fun' group, which is a lovely bunch of ladies - check us out!
The picture below peoples names is called an 'avatar' - 3fc provide some for you to choose from - I think you get it from your 'user control panel' , (the bit where you make up your profile). There is a section that says 'choose avatar' I think - I'm not explaining it very well, I'm sure someone else will do a better job!
all the best
